Variable storage shelving

ABSTRACT

Storage shelving includes at least two base elements consisting of an essentially horizontal base support and several storage grilles, whose side rails are arranged substantially vertically and whose grille bars run substantially perpendicular to the side rails. The storage grilles can be displaced about the longitudinal axis of the rails or about an axis lying parallel to the rails in different angular positions and the two or more base elements are rigidly and detachably interconnected. At least two storage grilles having side rails adjoin one another on each base support and either both or all side rails are fixed to a rod that projects essentially vertically from the base support, or one side rail is fixed to the base support and the second or additional side rail(s) is/are fixed to the first side rail.

The invention relates to a curing rack, especially for holding flat articles, such as sheets, battens, panels or the like, with the features cited in the preamble of claim 1.

Conventionally, curing racks are used for curing workpiece parts (especially sheet materials) in furniture production, especially in surface drying after painting.

In order to achieve maximum versatility of these curing racks for the most varied sizes of parts to be laid down, curing racks with four support grids (four grid bars per tier) are used. These curing racks are generally set up on a rectangular or U-shaped base frame. One problem is the not inconsiderable amount of space required for these curing racks when they are not needed. Telescoping/stackable curing racks save space only starting with the second carriage. Curing racks with an adjustable length generally have only two support grids. Curing racks which have an adjustable length and four support grids are equipped with one or more crossbars which impart the necessary stability to it. These crossbars require additional operating effort when the length is being adjusted. Since they can project to the outside when the length has been adjusted to be shorter, under certain circumstances they also constitute a barrier to the operators.

In a curing rack with two essentially horizontal base supports and at least two support grids, mounting these supports grid with the ability to turn around the lengthwise axis of the grid crossbeams with a fixing capacity is already known (DE 1 909 391 A). When the curing rack is not in use the support grids can be swivelled in. This configuration likewise reduces of the amount of space required when the curing rack is not being used. In order to mount the support grids with a turning capacity, however a rectangular base frame is necessary, the grid crossbeams being hung with upper and lower axle pins in the corresponding holes in the upper and lower beam of the base frame.

The object of the invention is to offer a variable curing rack which is easy to operate, with four support grids, and at the same time to enable an extremely small space requirement when not in use. The support grids are to be mountable without the need for a base frame so that precautions for adjusting the length of the curing rack are not limited by the base frame.

As claimed in the invention, this object is achieved by the features given in the characterizing part of claim 1.

So that there is a suitable support possibility due to the support grids which are directly next to one another, they are mounted such that they can be moved into different angular positions by simple manipulation. This execution makes it possible to combine the advantages of curing racks which are built on a fixed base frame, specifically to offer four support bars per tier, with the advantages of curing racks with an adjustable length, specifically an extremely small space requirement when they are not being used. At the same time the curing rack is characterized by its great variability and ease of operation. Moreover the support area can be enlarged in length over the amount possible by the adjustment element by the grid bars which can be positioned to the outside.

Other advantageous embodiments are the subject matter of the dependent claims.

The invention and other details of the invention are explained using the embodiments shown in the drawings, without being limited thereto.

FIGS. 1-3 show the curing rack as claimed in the invention in a front, side and top view in a first embodiment,

FIGS. 4 and 5 show details of the attachment of the support grids according to the first embodiment,

FIGS. 6-9 show different versions for connecting the base components,

FIGS. 10-12 show the curing rack as claimed in the invention in a second embodiment, and

FIG. 13 shows details of the mounting of the support grids according to another embodiment.

The curing rack consists of at least two base components which each consist of one horizontal base support 01 and several attachable support grids. The support grids consist of one grid crossbeam 09 which is located perpendicular to the base support 01 and several grid bars 11 which are mounted essentially at a right angle to the grid crosspieces 09.

In the first embodiment as shown in FIGS. 1-5, the support grids can be mounted by way of a bar 02 which projects vertically upward and which is mounted on the base support 01 (FIG. 2, side view). Alternatively the support grids can be attached directly to the base support 01; attachment can be effected pivotally by means of a clamp 22; other support grids can be attached to this support grid (FIGS. 10-12).

On the ends of the horizontal base support 01 there are standing surfaces 03 or rollers 04 can be attached.

The base components are rigidly and detachably connected to one another; the connecting components are preferably made adjustable.

The grid crossbeams 09 are adjustably connected to the base support 01 such that the grid bars 11 can be positioned in different angular positions against one another (FIG. 3, top view). This takes place preferably by means of clamps 10 which are welded on the grid crossbeam 09 and which can be clamped on the bar 02 attached to the base support 01 or on the grid crossbeam 09 attached to the base support 01. The support grids can thus be continuously swivelled (FIG. 3 top view and FIG. 5 detailed extract—different attainable positions of the support grids are shown by the broken lines).

Other embodiments with which the support grids can be mounted on the bar 02 attached to the base support 01 or to the grid crossbeam 09 which is attached to the base support 01 are:

A) By strap hinges 21 FIGS. (10-12).

B) By hooks 24 which fit into a row of eyes 23 (FIG. 10).

D) [sic] By screwing down, in which the screws can be attached in a row of threads (no figure).

The preferred execution of the connecting components of the base components are scissor braces 05 (FIG. 1—The broken lines show the position of the smallest adjustable distance of the base components to one another), they also keep the base components parallel during the adjustment process and can be fixed in different positions. The scissor braces 05 are preferably connected on the bottom end by means of a hinge 06 to the base components (FIG. 5 top view—the top half of the scissor braces 05 with the clamp is omitted in this representation). In the middle they are fixed against one another for example by means of an inserted screw 07. The top end can be fixed on a vertical guide rail in different positions. The preferred embodiment of top mounting consists in a clamp 08 which can be moved on the vertical rod 02 (FIG. 4 top view—the lower hinge is omitted in this representation).

Other embodiments for the connection of the base components are:

A) multiple scissor braces 13 (FIG. 6), here a greater distance of the base components to one another can be attained relative to the version with single scissor braces.

B) C-shaped spacer bars 14 (FIGS. 11+12) which can be inserted into sleeves which are mounted on the base components, and can be fixed for example by attachment screws 15. In the illustrated case the base support 01 is used as a sleeve. This version ensures fixed distances of the base components. These spacer bars can be made for example in different standard lengths.

C) Straight spacer bars 16 (FIG. 7) which can be inserted into sleeves 17 on the base components and can be fixed for example by attachment screws 15.

D) Spacer bars 18 which are made telescoping (FIG. 8).

E) Articulated braces 19 (FIG. 9) where the articulations 20 can be fixed for example by attachment screws 15.

The base supports 01 are made telescoping in the area of the grid crossbeam attachment (FIG. 2—The telescoping base support 12 which has been pulled out and the support grids which are swivelled to the rear are shown by the broken lines). When the telescoping base supports 12 have been pulled out and the support grids have been swivelled to the rear the curing rack can be loaded on both sides without tipping (FIGS. 2 and 3).
